Title: Pneumatic control module assembly
Inventor: BOUTEILLE D
IPC: F15B11/00
Filed: 1975-03-13
Abstract: 1504191 Pipe couplings LA TELEMECANIQUE ELECTRIQUE 13 March 1975 [11 April 1974] 10484/75 Heading F2G Adjacent fluid control module bases 1, 1<SP>1</SP> each define two housing cavities wherein coupling devices 3 are receivable to effect coupling of the modules and fluid communication therebetween; with the coupling member being further receivable into a second position wherein a contribution is made to the sealing of a module fluid orifice if required. Coupling device 3 may be in the form of a plug having a flange and lip portion as shown each half portion of which is receivable into a corresponding cavity in adjacent modules to form a connection; an additional plug being receivable into an end orifice of a module base where a sealing ring completes sealing. Removable pneumatic components 5, 5<SP>1</SP> are receivable on to the bases to complete the modules. In an alternative coupling arrangement (Fig. 4) latch members 13 are pivotally fixed within one of the cavities of each module base and via hook means 14 may engage a shoulder 15 in an adjacent module base cavity to effect coupling or may alternatively pivot to a second locking position wherein a lateral protuberance 17 on the latch co-operates with a sealing ring to effect sealing of an end orifice. In a further arrangement affording a more rigid coupling, the housing cavities are confined to the plane of coupling, a coupling member 18 (Fig. 5) in the form of a T-section slider is received within a mortise aperture defined by juxtaposed modules and lateral tongues 23 on the slider overlap shelf portions 24 to effect locking of the adjacent modules. Alternatively the slider may have a double dove-tail section and be received into a mortise aperture defined by juxtaposed dovetail cavities of adjacent modules to form a connecting key therebetween. In the latter case means are provided to limit withdrawal of the slider, and both forms of slider terminate in a half collar 40 (Fig. 5) which may engage an annular groove in a plug stop 41 to urge the stop into sealing relationship with an end orifice. Sealing of communicating orifices of adjacent modules may be effected by the compression of a sealing ring (Fig. 2) between adjacent orifices or by means of a communicating pipe portion (not shown) sealed with sealing rings. Alternatively a spigot and socket fluid communication between adjacent modules may be employed (Fig. 4).

Title: Improvements relating to the control of dynamo electric machines
IPC: H02J3/46
Filed: 1930-04-02
Abstract: 358,035. Running generators in parallel. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and WHITAKER, F. P., 237, Clifton Road, Rugby. April 2, 1930, No. 10486. [Class 38 (iv).] Regulation, automatic.-Where a number of similar dynamo-electric machines G1, G2 share a bus-bar load and have field rheostats R mechanically connected to a common control device M, an auxiliary rheostat A in series or shunt with each main rheostat is individually and automatically controlled so that the excitation of a single machine may be adjusted for connection and disconnection with the bus-bars. A two-position relay 15 controls a pilot motor N actuating an auxiliary rheostat, so that when the voltage of an incoming machine is above that of the bus-bars it is automatically reduced to a value equal to or somewhat greater than the bus-bar volts, whereupon the relay moves to its other position and effects closure of the contactor C connecting the machine to the bus-bars. Auxiliary contacts on this contactor then cause the pilot motor to eliminatethe auxiliary resistance A. For disconnection a circuit is closed manually at Q through normally closed contacts of a further two-position relay 13 responsive to the output of the machine, which circuit causes the pilot motor N to insert the auxiliary resistance and cause the machine output to be reduced until the relay 13 drops and closes a circuit through its other contacts and a further relay 12 to de-energize the closing coil of the machine contactor C, whereupon the pilot motor is reversed to cut out the auxiliary rheostat and the relay 12 is de-energized.

Patent GB-109480-A (GB)
IPC: B41B5/12
Abstract: 109,480. Lanston Monotype Corporation, (Lanston Monotype Machine Co.). Sept. 13, 1916. Single-type composing and casting machine matrices.-Relates to rules &c. made in continuous strip form by successively casting increments which are fused to the ends of previously cast ones, as set out in Specification 7202/15. According to the present invention, each increment is cast in a mould cavity of varying height so that as the metal freezes and cools the final result will be a strip of uniform height the edge of which will form a perfect printing surface. Fig. 4 shows a mould provided with a mould blade 12 and metal injection channel 10 and also with a matrix 11 having a recess 13 which varies in depth to provide the desired mould cavity. The variation is shown exaggerated. The recess 13 preferably extends beyond the advanced wall 15 of the mould cavity to give clearance to the metal as it is pushed forwards. The invention is applicable to the production of borders or ornamental rules having true printing-surfaces. In the preferred method of making the matrices, the recess is first made of uniform depth throughout and the matrix is subsequently bent slightly, a transverse cut 14 facilitating the operation. After bending, the top and bottom faces are dressed off parallel with each other.

Title: Improvements in voltage regulator devices
IPC: G05F1/14
Filed: 1954-04-14
Abstract: 775,741. Transformers. FOSTER TRANSFORMERS, Ltd., and JENNINGS, R. E. April 13, 1955 [April 14, 1954], No. 11011/54. Class 38 (2). A voltage regulating device incorporating an on-load transformer tap-changing system comprises coarse and fine switches mechanically interconnected through a reduction gear, the coarse switch co-operating with tappings on the transformer and the fine switch supplied from further transformer winding and arranged to inject a variable voltage into the output circuit through an auxiliary transformer. A coarse switch comprises two contacts 8, 9 moving together over studs 2 ... 7 connected to tappings on a transformer winding T, the contacts 8, 9 being so arranged that neither can bridge two successive studs. A fine switch 10, which is mechanically coupled to the coarse switch has a circular row of contact studs and is directly coupled to a switching device 11 which comprises a pair of semi-circular elements 12, 13 and a co-operating brush 14. The circular row of contact studs are connected to tappings on a further transformer winding 15, half the number of studs being connected to the tappings in the reverse order to the other half. The gearing between the coarse and fine switches is such that the fine switch makes one revolution whilst the coarse switch moves from one pair of studs to the next pair. When both contacts 8, 9 engage the stud 2 and the winding 15 is injecting no voltage into the circuit the output voltage O is zero. As the fine switch begins to move a voltage from the winding 15 is applied to the primary winding 19 of an auxiliary transformer and by means of the secondary windings 17, 18 is applied to the output circuit O. When the fine switch has moved half a revolution a voltage v/2 (where v is the movement between tappings on the transformer winding T) is applied to the output circuit O. The windings 17, 18 are so connected that the voltage between the segments 12, 13 is now zero so that the brush 14 can bridge the gap between them without a large flow of current. At this point the contact 9 moves to stud 3 but the increment v of the winding T is opposed by the voltage v/2 of the winding 18. During the next half-revolution of the fine switch the opposing voltage of v/2 falls to zero, thus the voltage applied to the output circuit O becomes v. At this point again no voltage exists between the segments 12, 13 and the brush 14 bridges the gap under no current conditions. Further revolution of the fine switch will increase the voltage applied to the output circuit O in a similar manner. Specifications 607,347, 619,474, [Group XXXVII], and 675,615 are referred to.

Filed: 1956-04-11
Abstract: 814,315. Phase detectors; discharge tube gating circuits; pulse code modulation systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 11, 1956 [April 14, 1955], No. 11017/56. Classes 40 (5) and 40 (6). The voltage Vc across a capacitor 34 not shunted by any D.C. conducting path is varied stepwise by secondary emission from an anode 33 or other electrode to which it is connected at instants when the valve is rendered conductive by pulses 2 applied to its grid 30, and takes successive values depending on the instantaneous voltage on the screen grid 27 at these instants and such that the net anode current becomes zero at these instants. To this end, the anode and screen grid 27 are given initial dynatron voltages within ranges, e.g. Va 1  to Va 2  and Vg 2  = 50-60 volts, Fig. 2, such that the net anode current i a  to the capacitor 34 changes linearly from a negative to a positive value over the anode voltage range Va 1 -Va 2  for constant voltages on screen grid 27. The anode may also be connected through a normally blocked diode 40 to a positive voltage Vo less than that of the anode so that the output voltage Vc 1  is never ambiguous due to the dynatron characteristic. The system may be applied to phase detection between the incoming synchronizing pulses 2 and a sawtooth waveform 26 in a television receiver derived by applying line deflection flyback pulses to an integrating circuit 25, 25a, 24, the output voltage Vc being then applied to a timebase generator, e.g. cathode-coupled multivibrator 5, to stabilize the line frequency and phase. Alternatively the circuit may be applied to sampling intermittently an audio voltage in a pulse code modulation system, or to automatic gain control, or to continuously measuring a supply voltage. In a modification the pulses 2 are negative going and applied to the cathode of a valve with grounded grid. In a further modification the pulses 44 are superimposed on a sawtooth wave 45 (Fig. 4) and applied through a cathode follower 49 to the grid of a triode 43 rendered conductive only during the pulse, the secondary emission anode and capacitor 34 acquiring a voltage Vc dependent on the instantaneous value of the sawtooth wave.

Title: Improvements in and relating to fuel injectior devices for internal combustion engines
IPC: F02M57/02
Filed: 1930-04-09
Abstract: 343,378. Fuel pumps for internalcombustion engines. LARSEN, S. A., 2, Brigadegaarden, Copenhagen. April 9, 1930, No. 11256. [Class 102 (i).] A pressure accumulator charged by a fuel pump commences to operate when the pressure in the system is reduced and isolates the charge of fuel to be injected into the engine. A fuel pump 1 has an over. flow piston valve 6 provided with a face 7 limited by an oblique edge 8 and a level cut-off edge 9, pivotally mounted on a cam-actuated crossbeam 15 carrying a guide rod 17 connected through a regulating-arm 19 to the engine governor. The valve controls a byepass 12 which communicates with the suction chamber 14 of the pump to stop the delivery of fuel to the housing 4 through the pipe 3. The pump ensures that fuel injection always takes place at the same time, independent of the amount of the fuel injected. The pressure accumulator comprises a spring-loaded piston 21 which, at its lower end, encloses the enlarged head 26 of another piston 27 of smaller diameter by a ring 37 screwed into the piston 21, and flat seating surfaces 25, 28 are formed on the bottom of the piston 21 and the head 26. During the delivery stroke of the pump, fuel passes the groove 30, filling the chamber 32 and raising the piston 21 against the compression of the spring thereby raising the piston 27. As the piston 27 travels upward, communication between the groove 30 and the channel 32 is cut off, fuel then flowing to 32 through chambers 34, 24 and the bore 29. When the byepass operates, the spring forces the seatings 25, 28 into contact, isolates the fuel in the cavity 32 and the passage 33, and injects it through the spring-loaded fuel valve 39 and nozzle 44 into the combustion chamber until the groove 30 communicates with the chamber 32 again, when injection ceases. In a modification, the accumulator piston 21 may be loaded by a pressure medium instead of by a spring. In another modification, Fig. 3, two pumps 1 deliver fuel to pressure accumulators 4, in which the pistons 21 and the fuel valves 56 are loaded by compressed air supplied by a compresser 53, the valves 56 being separated from the accumulators. A pressure-regulating device, comprising a spring- loaded valve 59 controlling the communication of the pressure pipe 54 with a release passage 48, is adjusted by a lever 61 and a handle 62 identical with the speed-regulating handle for the fuel supply to the engine. In a further modification, the accumulator 4 is connected with the pressure piping, while the fuel valve is loaded by a spring &c. The compressed air may be replaced by liquid under pressure.
